Hey, I did not notice, but that's the case.
It is clearly intentional, probably to reflect that data are updated once a day, so what you get is not the last 24 hours (from 10 am yesterday to 10 am today when you look at it).
So it is more appropriate to say that' yesterday, from midnight to midnight.
However, I noticed the counter may tell a positive number of units but none shown in graphics.
I just filed a bug report – FB15722868
